Less horsepower and less torque. Why go backwards?
If anyone is interested in a stroker crank, PM me, and I will check out they still do so, and get you the details.
That is a crankshaft that has a longer stroke than the original. This increases displacement. Stroker cranks often increase torque dramaticaly at the expense of a reduced top-end RPM.
When top end rpm is only 5500rpm anyway though, no loss would be in that range, maybe 7500rpm + but a 6500rpm rev limiter on a 4.5 would also help power 
Having the cams re ground is also a cheap exercise [aprox $100 ea here], for more torque, and can be done by any cam grinder, though some research on the best grind to suit low down torque, and how far advanced to install them, or have them ground may need to be followed up.
I believe at least one 4.5 lt has been taken out to 6.0lt + but required custom pistons to suit the rod lengths required.

Hi Darren,
Do post the result on what you find out about the stroker crank.

Hey Darren/Shed-Dude...did you ever find out any more info about these 4.5L stroker cranks?97 FZJ80 said:
Thanks,

Kinda off topic, but has anyone ever put a Ford 302 in a 60 or 80? I have 2 junker f-150s, they both run, but the trannys and t-cases are shot...could be a summer project if I find a good deal on a beater 60 or 80.

Advanced Adapters sells a kit for a Ford small block to LC 4-speed, so a 60 would be you're best bet.alkaline747trio said:

Has anyone stuffed a Buick/LR 4.6 (all alum engine) in an 80? Just curious, 'cause I got a long block that's just taking up valuable shelf space!
V8J80. I like the V8. It works for me.
TLC4X4.com in SoCal has done several V8 swaps in early model 80's.
wasnt someone in here doing or going to do a tundra V8 swap into their 80 or have i just lost my mind?.... id love to see that if it has been done.
Yeah I have done one. The truck has almost 7000 miles on it now with no problems. It is running all the tundra electronics and the check engine light hasn't even come on yet! The truck ran awesome, but a little spendy. Look at the following link for details

Will,
[on soapbox]
I reread that link and would like to offer you an apology for the behaviour of some of the guys in that thread. We've had hi-jacks before but that was really sad; especially considering the outstanding topic that you were documenting for us. That is the first and only Toyota V8 swap into an 80 series that I have seen. I was embarressed to see how many times seasoned forum members were trying to take that thread to the trash heap.
If a forum mod is reading this then I plead with them to go back and delete those irrelevant and irreverant posts.

Thanks again for your efforts to document a great upgrade that many future 80 owners will consider and others will follow your project.

I had Ron at "A Breath of Fresh Air" automotive do the install (Concord, Ca.). A lack of time on my part was the reason for having someone else do the job. All things considered, he did a nicer job than I would have. Ron is an ace mechanic who has been specializing in Cruisers for 20-30 years. Lots of 40 and 60 V-8 swaps. This was his first 80 series and he wanted to do a 700R4 with selectable hubs, but I wanted to keep the full time 4wd with the A440F, so we went that route with an adapter. I also had the ARB's installed f&r, dual batteries, and a killer exhaust system with a magnaflow muffler. I can now install the sliders with no exhaust/cat problems. All of this with the 350tbi with late 60's ram's horn exhaust manifolds installed for $10,500. Sure it's a chunk of change, but I'm running around 300 hp and a boat load of torque. Gas mileage has slightly improved as well. Man-a-Fre quoted me $12,000 plus for just the engine swap alone (350tbi) and said they weren't sure what to do with the smog. Very reassuring. Everyone else wanted $15k+ for the engine only. Vortecs started at $18k for the engine swap alone, and up to $25k. Getting the ARB's, 350tbi, custom exhaust from the high performance manifolds to the tail pipe, dual electric fans on the stock radiator (actually an all metal aftermarket), dual battery set up, frony and rear ARB lockers, and the works for $10.5k seemed like a killer deal. Sure you can get a used FZJ and performance will be similar and a little smoother, but the power is just not there. A s/c engine will wear quicker than a standard 350tbi. I already had the truck and the head was cracked with a $2700 Toyota quote to replace the head on a 250,000 mile block that would need rebuilding soon anyway. When this 350 dies, I'll pick up another for $800 at a parts yard and go another 100-150K. I figure that getting same day parts, increased gas mileage and power, cheap replacement engines, and pimp factor made the swap worthwhile. I considered a 6.5td but the fuel injector issues and lack of longevity made me go for the 350. More power, fairly similar gas mileage, and same life expectancy made the 350 the best choice. I was able to use the original fuel tank and engine vacuum for brake boost. If I get bored with the 350 in the future, the engine mounts are the same for a 454 or a 6.5td. Who knows, in another 100-200k miles, maybe I'll try something else. The engine is lighter than the 3FE and it isn't nearly as smooth or quiet, but with 35" swampers in the works, who cares. Not me.

Hey White Shark, what kind of mileage are you getting? You said fairly similar . . . but how similar?

I saw your 80 at Ron's shop a whil back gettin' that 350 done, looked pretty sweet. He did a 350 and 4 speed for me in my 40 when my F motort ceased over the summer. The job was perfect and very reasonably priced.
